Title: Paper machine - utilises a gap-former having two wires with suspension sprayed between them and then passing over cross-rail with convex surfaces
Inventor: WANKE WILHELM
IPC: D21F9/00
Filed: 1993-09-22
Abstract: A double wire on a paper machine is constructed as a gap-former. The suspension is sprayed into the gap between two wires or similar water extn. material. There is at least one cross-rail beneath the bottom wire for water extn.. The profile of the cross-rail begins with a convex shape and having two radii in the direction of the run of paper. The second radius is larger than the first. Pref. the two wires have water extn. from the suspension and a paper formation in direction with thickness which is compressed in the gap. At the beginning of the area of the cross-rail which has a smaller radius, the water is extracted below, in front of it, without forming ridges, or a wave which shows as a fault in the paper. The second area has a radius which is larger. There is water extn. above the top wire, which provides adequate fluid to enable the bottom wire to glide over the cross-rail. The system may be formed into a series of water extn. points on the machine. It is necessary for the return rollers for the wires to be set to give the required angle in approaching the gap former. ADVANTAGE - The first radius convex eliminates the need for a suction roll. The paper is well formed and has a satisfactory consistency. A waveform in the paper is avoided. The cross rail does not erode quickly.
Patent DE-4334863-A1 (DE)
Title: Stalling protection (lock-up protection) for an electric tool
Inventor: HAERLE VINZENZ DIPL ING
IPC: H02P7/285
Filed: 1993-10-13
Abstract: A protection device for an electric tool is proposed, in the case of which the electric tool is switched off if the speed falls below a predetermined minimum rotation speed and if a predetermined torque has not been reached. This can become important particularly in the case of battery-operated electric tools such as drills and screwdrivers, since the predetermined switch-off torque is not reached if said predetermined switch-off torque is too great or the batteries are partially discharged. The rotation speed of the motor would then drop severely and damage would be caused because the current continued to flow. The battery would likewise be damaged. By switching off the rotation speed for example in the region of zero revolutions per minute, both the motor and the battery are protected.   <IMAGE>
